我更新了Nifty到v.1.4.2，Jogamp到v.2.4.0.，Java到jdk-11.0.2。更新前代码：

public class ISOView extends Object2D
{
  private IViewManipulation viewerInteraction;
  private IRenderEvent renderEvent;
  private ISOViewNiftyController isoNiftyController;
  private JoglInputSystem inputSystem;
  private Nifty nifty;

  public ISOView(IViewManipulation viewerInteraction, IRenderEvent renderEvent) 
  {
    super(RenderOption.TOP);
    this.renderEvent = renderEvent;
    this.viewerInteraction = viewerInteraction;
  }

  @Override
  public void render(GL gl, RenderParameters params, boolean selection)
  {
    if( params == null || params.getCamera() == null || !params.getCamera().hasFrustum() )
      return;
    
    GL2 gl2 = OpenGLUtil.getMinGL(gl);
    renderNifty(gl2, selection);
    isoNiftyController.update();
  }

  private void renderNifty(GL2 gl2, boolean selection)
  {
    if (ISOViewNiftyController.isNiftyUsed()) {
      // some code
    }
  }

  private void initNifty()
  {
    Logger.getLogger("de.lessvoid").setLevel(Level.OFF);
    inputSystem = new JoglInputSystem();
    nifty = new Nifty(new JoglRenderDevice(), new NullSoundDevice(), inputSystem, new AccurateTimeProvider());
    // other code
  }

  @Override
  public void cleanUp(GL gl)
  {
    // TODO Auto-generated method stub

  }

  public JoglInputSystem getInputSystem()
  {
    return inputSystem;
  }

  @Override
  public boolean belongsToScene(SceneType type)
  {
    // some code
  }
  
  @Override
  public void dispose( BaseViewer baseViewer )
  {
    // some code
  }
}

字符串
现在我有两个问题：

• 创建JoglInputSystem，它接受新参数
• 创建Nifty，它的JoglRenderDevice()方法已被弃用。

新代码：

private void initNifty(){
  Logger.getLogger("de.lessvoid").setLevel(Level.OFF);
  com.jogamp.newt.Window newtWindow = null;//Fix!!!
  inputSystem = new JoglInputSystem(newtWindow);
  de.lessvoid.nifty.spi.render.RenderDevice renderDevice = null;//Fix!!!
  nifty = new Nifty(renderDevice, new NullSoundDevice(), inputSystem, new AccurateTimeProvider());
  // some code
}

有人能帮忙吗？Using Eclipse IDE for RCP and RAP Developers，版本：2020-06（4.16.0），赢10
我试过了：

GLCapabilities caps = new GLCapabilities(GLProfile.getMaxProgrammable(true));

GLWindow glW = GLWindow.create(caps);// implements com.jogamp.newt.Window
inputSystem = new JoglInputSystem(glW);

有创建一些JoglInputSystem，我不知道如果正确的一个。但我不知道，如何创建一个Nifty。要创建它，我需要RenderDevice。这是一个只由两个类实现的接口。所以我创建了ScalingRenderDevice。要做到这一点，我需要NiftyRenderEngine。为此，我需要NiftyRenderEngineImpl，我开始了，因为我再次需要RenderDevice。

Nifty(RenderDevice newRenderDevice, SoundDevice newSoundDevice, InputSystem newInputSystem, TimeProvider newTimeProvider) 
    Interface RenderDevice - All Known Implementing Classes:
        BatchRenderDevice
            BatchRenderDevice(BatchRenderBackend renderBackend)
            BatchRenderDevice(BatchRenderBackend renderBackend, BatchRenderConfiguration renderConfig)
        ScalingRenderDevice
            ScalingRenderDevice(NiftyRenderEngine renderEngine, RenderDevice interal)
                Interface NiftyRenderEngine - All Known Implementing Classes:
                    NiftyRenderEngineImpl(RenderDevice renderDeviceParam)
